Using the quadratic formula \( x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a} \):

1. Identify coefficients:

\[

a=3, \quad b=-2, \quad c=-1

\]

2. Calculate discriminant:

\[

\Delta = (-2)^2 - 4 \times 3 \times (-1) = 4 + 12 = 16

\]

3. Find roots:

\[

x = \frac{2 \pm \sqrt{16}}{2 \times 3} = \frac{2 \pm 4}{6}

\]

4. Solutions:

• \( x = \frac{2 + 4}{6} = 1 \)

|--------|--------|

| -3 | -5 |

| -2 | -3 |

| -1 | -1 |

| 0 | 1 |

| 1 | 3 |

| 2 | 5 |

| 3 | 7 |

2. Plot these points and draw the straight line.
